the machine is a pipe 1 passes, said pipe being 7 whereby the section onthe line .the material to be reduced is The pipes 9 snrnna'rme nnvxcn.

To all whom it may concern:

Be it known that I, Enwann J. S'rncK'Ln, a citizen of 'the UnitedStates, residing at county of Lee, State of have invented a certain newan useful Improvement in Separating Devices, of which thefollowing is afull, clear, and exact description, such as will enable othersskilled'in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, forming part 01 thisspecification, in which-- Figure 1 is an endelevational view of myimproved separatingapparatus. Fig. 2 is a side elevationalview of thesame partly in section. Fig. 3 is a top plan view partly. in 3-3 of Fig..2.

This invention relates to a new and useful improvement in separatingapparatus designed particularly for'the. separation of particles ofmaterlal reduced by some sort of reducing machine such as a crusher -orpulveriz'er, the object being ,to return the coarser particles ofmaterial to the mill for further reduction and to collect the finerIllinois,

particles as afinished product.

Inthe drawings 1 .indicates a--reducing machine of any well known type.into which 5 fed. through the spout- 2. Leading from thebottom of orconduit 3' through which the material reduced inthe machine preferablyinclined asshown in F1g.'2.' Pipe 3 discharges into a fan shapedspreading member 4, (see Fig. the lower wall of which is. provided withdiverging ribs 5 and one section of which lower wall, together with itsconnected di-- verging ribs, 1s hinged at 6, such hin d portion beingadjustable by means 0 av threaded bolt 7. Of course the ribs 5 areseparated at the hinge point, but are substantially continuations of thediverging ribs attachedto the solid portion of this flaring spreadingpipe. The hinged, portion of the spreading pipe is-located in achamber-8 in which chamber are arranged airinlet pipes 9 each havingnozzles 10 whose discharge ends'arezflat ed-so as to'emit'substantiallycontinuous sheets of air at. an angle to each other meeting practicallyat the lower edge of thefhinged portion of the angularly disposedspreading w with theirflattened mounted in the.

emitted therefrom can be adjusted. There *areremovable covers 9 on theends of the pipes which enable access to be gained the interiors thereoffrom the outside for cleaning purposes. This may be necessary on accountof the dust settling in the pipes 9. r The pipe 11 leads from thetop ofthe separating chamber 8 into the eye a fan 12 whence the dust laden airis projected by dust collector 13 of the well lmown cyclone type. Theparticles of dust thus drawn from the separating chamber by the fan arecollected in the dust collecting chamber 13' the trough 14: in which islocated a spiral blade15 for conducting the material into a chamber 16where it may be elevated by suitable buckets 17 and deposited in astoragebin, not shown. e air pressure in the dust collector 13 escapesthrough a discharge pipe per controlled pipe vent 19 located at somesuitable point in its length whereby ressure in the pipe 18 may beregulated. ipe 18- leads back to the separating chamber 8 and suppliesair to the pipes 9 heretofore referred to.

Only the finer particles of material can be drawn into the pipe 11 anymaterial passes with the air from the dust collector through the pipe18, it is obvious that such dust laden air will be and deposited intochamber-an eventually be'collected. In heavy particles of material frombeing drawn. into the fan, I adjustable baflle plates 11 said latesbeing inclined in the opposite directions so as to deflect the air andcause the heavier particles of materi verted so that they will have anopportumty of falling back into The heavier particles, up through thepipe 11' fall into the bottom 0 the separating c 20, where a spiral 21conveys or collectingchamber to be buckets 22 and returned by a suitabledown 18 having a damby the fan and if the blower'tangentially into aorder to prevent preferably arrange in the pipe 11,

The nozzles are directed so that the point of the intersection of thesheets of air emitted therefrom meet substantially at, or slightlybelow, the point of discharge or lower edge of the hinged wall of theseparatspout. By, this arrangeing or spreadin "ment, I am enab ed tostrike the fallingparticles-on both sides with the result that the finerparticles are carried up with the air current and delivered to the dustcollector. The troughs15 and 21 are so constructed that the screwconveyers arranged therein,

What I claim is: Y 1. A separating apparatus of the character described,comprising a separating chamber having a spreader for conducting thematerial posed nozzles for emitting blasts of air on opposite sides ofthe material as it leaves.

2. An apparatus of the character described comprising a separatingchamber, a
